' COTTON-SCRAPER ATTACHMENT.

`Specification of Letters Patent.

Patented Apr. 4;, 1922.

Application filed December 15, 1929. Serial No. 430,912.

To all whom t may camcom.'

Be it known that I, GUY It TUCKER, a citizen of the United States,residing at Citra, in the county of Hughes-.and @tate of Oklahoma, haveinvented certain new and useful Improvements in Cotton-ScraperAttachments, of which the following is a specification. n

This invention relates to scraper blades and more particularly to ascraper blade attachment whereby the earth working ele` ment may beadjustably mounted in different angular positions to meet thenecessities of the desired cultivation.

One of the objects of the invention is directed to a scraper bladeattachment capable of universal use in connection with various types ofcultivator blades, said device being constructed and arranged forattachment and detachment to a support or foot piece of the moderncultivating machine.

A still further object of the invention re sides in the provision of ascraper blade attachment having a novel form of clamping means forpositively locking and retaining the blade in various predeterminedangular positions without 'effecting the eliciency and operation of themachine.

Another and important object of the invention will, be found in thesimplicity of construction, reliability of its several parts, which maybe easily assembled by the unskilled mechanic, capable of beingmanufactured at a comparatively low cost, and the universal use of whichthe same is applicable.

With these objects in view and others which will be manifest andsuggested as the nature and purpose of my invention are reA vealed inthe following specification and drawing wherein I have shown apractical, yet preferred embodiment thereof.

Figure 1 is a rear view partly broken away showing the attachment whenassembled.

Fig. 2 is a View taken on the line 2-2 of Fig.

Fiom 8 is a view taken on the line 3--8 of Fig. 1.

Fig. 1 is a similar view taken on the line 4 4 of Fig. 1.

Referring now in particular to the illustration wherein I have shown mynovel and improved scraper blade attachment mounted on the foot piece orstandard l of a modern cultivator, it being understood thatk the rightand left scraperblades are adapted to be used in thevcultivation of rowsor hills. It will be noted that the rear face 2 of the scraper. blade3is adjustably attached tol a curved cuff designated by the 4numeral #lawhich cuff is provided with a reduced upper extension 5 havinganelongated, elliptical slot 6. A threaded bolt 7uhaving aulocking nut andwasher 6 thereon passes through an aperture 10 usually provided in thescraper blade, said bolt passing also through the elongated slot 6permitting the ready adjustment of the blade subsequently to be referredto. Y

The culi' as shown is provided with another aperture 11 extendingtherethrough near its lower portion and receives a rivet 12 passingthrough an aperture 13 in the scraper b ade retaining the said bolt andcuff in locked position, the head 14 of said bolt being counter-sunk inthe recess 15 as clearly shown in Fig. 2. rThe cud is also provided withan enlarged intermediate elongated curved recess 16 which receives thetransverse bolt 17 passing through an aperture in the curved clampingmember 18 and the foot piece l1 where the said bolt is secured by a nutand washer 19, 20, also shown in Fig. 3 of the drawing. The curved faceof the culf member is preferably corrugated as at 21 for lockingengagement with the serrations 22 of the curved clamping member. Y

In accordance with the above structural arrangement, it will be readilyapparent that by loosening the bolt and nut 17,v 19 and of course, thebolt and nut passing through the elongated slot 6, the scraper blade maybe raised or lowered to the desired angle with respect to the ground toeffect the necessary scraping action of the blade. Furthermore, theserrated locking clam also permits the blade to be turned on itsvertical axis with' respect to the foot piece or support in the mannershown by dotted lines in Fig. 3.

In the accompanying drawing, I have illustrated my invention embodied inone form by way of example, and which in pra-ctice has been found to behighly satisfactory in obtaining the desired results. It will be obvioushowever that other embodiments may be adopted, and that. various changesin the details of construction may be resorted to by those skilled inthe art without departing from the spirit end scope of the invention. Itis furthermore understood that the invention is not necessarily limitedor restricted to the precise elements shown except in so fer as suchVlimitations are s cled in the subject matter being c aimed.

I have shown the curved oulf and clamp ing member used in connectionwith a souper blade but it is to be understood however, that theinvention is not necessarily limited to the particular type of blade.employed 'since it is capable of use in oonnection wtlhvzrous types ofcultivating tools, as will berewdily apparent to those skilled in thenrt. Y Y

What I claim is:

A cltivator blade nttafchment in combinetion with e. support comprisinga curved culi' member, havlng un offset reduced upper extension providedwith un elliptical slot therein, fastening elements assing throu l1egel-tures in the blade and s ot for vertical y a justing said blade,said cu member being also provided with an elongated, lnter- 25 mediaterecess and oorrugations on its in` ner face, a curved clamping memberhaving cooperating serretions seated entirely withs in the inner face ofthe ouf, and a central i pivot bolt `extendirqg through the mu, 30clamps and supports whereby the clamping member and the blade may beoircumferentially adjusted.

In testimony whereof, I aixmy signetnre hereto.
